Abstract

n this study, a porous NiAl coated nickel mesh electrode (EPS-NA) was designed by plasma spraying and alkaline etching. The sprayed ratio of Ni and Al plays a vital role to obtain a superior and stable performance in both hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). The in-situ formed NiO phase were observed in the coating and significantly accelerate the HER kinetics by promoting the Volmer step.

等离子喷涂调节多孔NiAl涂层在镍网上的析氢和析氧性能

本研究采用等离子喷涂和碱性刻蚀的方法，设计了多孔NiAl包覆镍网电极（EPS-NA）。在析氢反应（HER）和析氧反应（OER）中，Ni和Al的喷射比例对获得优异稳定的性能起着至关重要的作用。在涂层中观察到原位形成的NiO相，并通过促进Volmer步骤显著加速HER动力学。
